Objective To investigate and analyze the prevalence of metabolic syndrome and its components among staffs of Guangdong. Methods One thousand six hundred and fifteen persons were enrolled in this survey. The medical check up data from the physical examination were analyzed. Results The prevalence of metabolic syndrome, obesity, hyper-triglyceridemia, hypo-HDL-C, hypertension, glucose metabolic disorder were 16.3% ,27.6% ,22.7%, 15.0% ,51.8%, 10.7% respectively. The MS prevalence was increased with aging. Prevalences of 0-5 MS components were 31.5% ,31.2% , 22.2% , 10.0% ,4.7%,0.3% respectively. It was significant difference between 2 groups that UA, ALT, AST, CHOL, LDL-ch (t value is 6. 473,4. 238,7. 406,6.810,8. 350, seperatly, P<0.01). Conclusions The prevalence of MS is high in the staffs of Guangdong. The blood pressure increasing prevalence was maximal. The other components prevalences were high too. MS tends to be a many data abnormality disease, early detection and intervention are important.

OBJECTIVE:To evaluate the utilization of blood lipid-lowering drugs in Haikou area.METHODS:The consumption sum,DDDs and DDC of blood lipid-lowering drugs in 2 hospitals of Haikou area from 2007 to 2009 were analyzed retrospectively.RESULTS:The consumption sum of blood lipid-lowering drugs in Haikou area increased year by year,up by 41.25% in 2008 than in 2007 and 28.96% in 2009 than in 2008.Blood lipid-lowering drugs were mainly atorvastatin,pravastatin,fluvastatin,simvastatin,bezafibrate.Atorvastatin took up the first place of the list of consumption sum and DDDs in past 3 years.CONCLUSION:Statins occupy the predominate place among blood lipid-lowering drugs and show potential in the market.

Objective To explore the effectiveness of defluoridization of water and the morbidity trends in endemic fluoroais areas in Yanqing county of Beijing, in order to provide the basis for the formulation of prevention and control measures. Methods In 2008, stratified random was used to collect water samples to detect the amount of drinking water fluoride in three villages(Gujiaying, Bojiying and Hujiaying) in Yanqing county using ion-selective electrode in both dry and rainy seasons. Sixty-three students in 8 - 12 years old and 664 adults over 16 years of age were determined of urinary fluoride, and examine the prevalence of dental fluorosis. ResultsThe fluorine content in drinking water in the dry and rainy seasons was (0.72 ± 0.12), (0.76 ± 0.18)mg/L, respectively. The median of fluorine content in urine of children was 1.11 mg/L with the range of 0.32 - 4.15 mg/L; the median of fluorine content in urine of adult was 1.42 mg/L with the range of 0.37 - 4.65 mg/L. The detection rate of dental fluorosis in children was 23.81%(15/63), dental fluorosis index was 0.45; the detection rate of dental fluorosis in adult was 54.97% (365/664), dental fluorosis index was 1.70. Conclusions Fluorine content in drinking water meets the national standard in Yanqing county. The morbidity of endemic fluorosis descends in some extent in a result of defluoredization.

Objective To understand current status of brucellosis infection in both human and animal in Yanqing County to get solid scientific basis for controlling the disease and to prevent the spread of epidemic.Methods Cluster sampling method was used in this survey in stock raisers and ELISA and SAT were performed to inspect serologic antibody of Brucella.At the same time an epidemic investigation was carried out,including the basic personal situation,occupational history,vaccination history,clinical symptom,and so on.Resutls In a total of 216 cow raisers whose blood Was detected,27 cases showed positive in titer test of Brucella antibody with a ratio of 12.50%.However,all the antibody carriers did not have any clinical symptoms.In all 2185 cows that were collected for antibody test,1488 cases had positive serological antibody with a ratio of 68.10%.And all the positive COWS also did not have any clinical symptoms.Conclusions The subclinical infection of brucellosis is rather high in Yanqing County's stock raisers.It is self-protection of the stock raisers,epidemic knowledge propaganda,serological surveillance in human and animal,immunize of healthy cows,and eliminate of diseased cows that are urgent in order to keep the public in health.

Non-coding RNAs (ncRNAs) are a large class of RNA molecules that do not encode proteins, regulate gene expressions multifacetedly, and influence the metabolism, proliferation, differentiation and apoptosis of cells as well as the occurrence and progression of tumors. Some of the ncRNAs act as cancer genes, such as miR-19a, miR-125b, miR-616, miR-7, miR-221, MALAT-1, and PRNCR1, which are upregulated in castration-resistant prostate cancer (CRPC) tissues or cell lines, and promote the development and progression of CRPC, some act as tumor suppressor genes, including miR-185, miR-342, miR-15, miR-16, and miR-146, which are downregulated in CRPC tissues or cell lines and inhibit or delay the occurrence of CRPC, and still others, such as miR-7, miR-19a, miR-125b, miR-221, and MALAT-1, are differentially expressed in the serum or tissue and can be used as potential biomarkers for the early diagnosis and prognosis of CRPC. This article presents an overview on the roles of ncRNAs in the occurrence, progression, diagnosis, and prognosis of CRPC and advances in their studies.

Pseudorabies is an economically important disease in a variety ot animals caused by pseudorabies virus. Since 2011, pseudorabies outbreaks occurred in many regions of China. Related researches on this virus become a hot topic in virology and veterinary. One of the difficulties for pseudorabies prevention and control is innate immune evasion. Explorations on this issue are conducive to the development of vaccine and drugs. Therefore, this review summarized the recent research progress on the mechanisms of pseudorabies virus innate immune evasion. Theoretical direction was provided on effetive prevention and control of pseudorabies owing to this review.

Light cannot be propagated within the range of photonic crystal band gaps. Based on this unique property, we proposed a method to improve anti-radiation capability through one-dimensional photonic crystal coating. Using transmission matrix method, we determined the appropriate dielectric materials, thickness and periodic numbers of photonic crystals through Matlab programming simulation. Then, compound one-dimensional photonic crystal coating was designed which was of high anti-radiation rate within the range of X-ray. As is shown through simulation experiments, the reflection rate against X-ray was higher than 90 percent, and the desired anti-radiation effect was achieved. Thus, this method is able to help solve the technical problems facing the inorganic lead glass such as thickness, weightiness, costliness, high lead equivalent, low transparency and high cost. This method has won China's national invention patent approval, and the patent number is 201220228549.2.

Objective:To improve the method for isolating platelet-rich plasma (PRP). Methods:Whole blood was collected from 8 healthy donors and then PRP was separated by both the tube method and the syringe method respectively. Samples were activated to get serum rich-in growth factors (SRGF).Platelets in the SRGF were counted and the level of TGF-?1 was assayed by enzyme-linked immunosorbent assay (ELISA).Results:The end product of syringe method has both a higher platelet count in PRP (P=0.003) and a higher level of TGF-?1 in SRGF(P=0.041) than that of tube method.Conclusion:The syringe method is an effective method in preparation of PRP.
